WebThe introduction of advanced technology nodes in deep UV (DUV) lithography (litho), involving multiple litho steps, has tightened the wafer on-product overlay specifications [1]. The industry trend already pushes … Lithography (from Ancient Greek λίθος, lithos 'stone', and γράφειν, graphein 'to write') is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and map…
